I doubt it. I do get many benefit and pleasure from my old friendship , and I love to maintain it. But it is almost impossible not to making new friend when you entering a new environment. Making new friend help you fit in new environment better, gives you new sight about the world. On the other hand , the old friends couldn’t become our old friends if we didn’t start to making new friends. Therefore making new friends is very important. However it’s true that friendship become more solid and reliable as time pass. We lose some friend because we didn’t touch for long time. So keep interacting with old friend are also important .
Anyway if we emphasize both quality and quantity of friendship, making new friend and maintain old friend are both important. It’s hard to put one on the top of another.
